摘要： A method and system for determining locations in a design of an assembly likely to result in buzz, rattle squeak (“BSR”), and/or other noise conditions. The invention uses a finite element model to represent a design. BSR effects are predicted based upon analysis performed on multiple design models. Users may engage in real-time “what if” analyses to determine the effects of various design and component changes on noise source characteristics. Additional intelligence may be applied to limit the number of model points subject to evaluation. Displacements, contact velocities, and force responses at selectively identified subsets of interesting points can evaluate noise characteristics. An “as designed” model may evaluate noise source characteristics at the beginning of the life of an assembly. Degraded models can determine the effects of aging and use. A restored model may evaluate the influence of optimal fastener design on BSR characteristics for assembly resulting from fastener degradation.

摘要： A method of automatically defining the spatial arrangement of structural components and optimizing the functional positions and/or quantities thereof is useful for design and production of an aircraft cabin. The basic aircraft type is input into a configuration tool of a data processing system. The aircraft-specific geometry is stored in, loaded from and represented by a drawing module of the system. The required components are geometrically defined by stored data and position rules, and are combined with the aircraft-specific geometry in the drawing module. The components and the aircraft-specific geometry are spatially optimally configured relative to each other according to a rule set which accounts for specific customer requirements, in the configuration tool. Production documents such as drawings and parts lists are automatically generated by a document generating tool of the system after inputting project-related data.

摘要： Systems and methods are provided for composite part design. One embodiment is an apparatus that designs a composite part. The apparatus includes a controller configured to generate a design for the part. The controller subdivides the part into blocks that each comprise a contiguous stack of layers within the part, identifies rules that constrain how layers that have different fiber orientations are stacked within the part, generates a guide for a block that prescribes a fiber orientation for each layer of the block, and identifies sublaminates comprising that are compatible with the guide for the block. The controller subdivides the part into panels, and selects one of the compatible sublaminates for one of the panels of the block, based on compatible sublaminates for neighboring panels. The apparatus also includes a memory configured to store the design for use by an Automated Fiber Placement (AFP) machine constructing the part.

摘要： In accordance with embodiments disclosed herein, there are provided methods, systems, and apparatuses for predicting whether a point on a computer-generated aircraft or vehicle surface is adjacent to laminar or turbulent flow is made using a transition prediction technique. A plurality of boundary-layer properties at the point are obtained from a steady-state solution of a fluid flow in a region adjacent to the point. Included in the list of boundary-layer properties are computed coefficients or weights of mode shapes that describe the boundary-layer profiles. A plurality of instability modes are obtained, each defined by one or more mode parameters. A vector of regressor weights is obtained for the known instability growth rates in a training dataset. For each instability mode in the plurality of instability modes, a covariance vector is determined, which is the covariance of a predicted local growth rate with the known instability growth rates. Each covariance vector is used with the vector of regressor weights to determine a predicted local growth rate at the point. Based on the predicted local growth rates, an n-factor envelope at the point is determined.

摘要： An aircraft designing apparatus receives set values of design parameters related to the shape of an intake duct, creates analysis models for an aerodynamic characteristic analysis and a radar-cross-section analysis by using the values of the design parameters, calculates aerodynamic characteristics and radar-cross-section characteristics of the intake duct, and determines whether or not this analytical result satisfies a preset design condition. If it is determined that the analytical result does not satisfy the design condition, the values of the design parameters are updated. The updating of the design parameters, the analyses of the aerodynamic characteristics and the radar-cross-section characteristics, and the determining process are repeated until it is determined that the analytical result satisfies the design condition.

摘要： A computer-implemented method for visualizing an object. Instructions identifying a hierarchy of image blocks and an action scheme are received. An image block in the hierarchy of image blocks is loaded to display an image corresponding to the image block to a user through a graphical user interface displayed on a display system. A number of image areas on the image are selectable. User input that selects an image area in the number of image areas is detected. Visualization information to be sent to a visualization system for use in visually presenting a portion of the data about the object of interest to the user through the graphical user interface is generated based on the image area selected.

摘要： A system and method for drag reduction allows thrust output, fuel efficiency or both to be maximized. Specifically, a rear portion of a body or motor vehicle may be modified to increase thrust output, fuel efficiency or both by creating a stagnation area, a suction inlet and a convex cusp area formed on the rear portion of the motor vehicle. Increasing the concavity or camber or sharpness of the radius of the stagnation area results in greater local pressure coefficient, which results in greater thrust output. The size and shape of the suction inlet and the convex cusp area will also have an effect on thrust output and fuel efficiency. A width and volume of an airplane fuselage may be increased.
